Background technology
Long Term Evolution (Long Term Evolution, LTE) wireless telecommunication system is a kind of advanced formula high-speed radio communication system that builds on the third generation mobile system (as global mobile communication system), it needs to support packet-switched transmission, and Radio Link control (Radio Link Control, RLC) protocol layer and medium access control (Medium Access Control, MAC) protocol layer can be integrated in same communication network unit, among the base station, and need separately not be positioned among base station (Node B) and the radio network controller (RNC), so system architecture is simpler.
The Long Term Evolution wireless telecommunication system have dynamic dispatching (Dynamic Scheduling, DS) and semi-persistent scheduling (Semi-Persistent Scheduling SPS) waits two kinds of scheduling modes.Dynamic dispatching is flow and the QoS requirement of network terminal according to client, dynamically assigns transfer resource and gives client, carries out Data Receiving or transmission so that client to be provided.Semi-persistent scheduling then is the upper level applications of network terminal for seeervice cycle property generation data, transmit technology (Voiceover Internet Protocol as internet protocol voice, VOIP), assign transfer resource with the fixed cycle and give client, reduce network terminal and on physical downlink control channel (PDCCH), send control information, and the usefulness of enhancement system call.In other words, semi-persistent scheduling provides the transfer resource of fixed cycle to client, so client do not need to monitor physical downlink control channel, can periodically transmit, and can determine to be all new transfer of data in the transmission in cycle each time.
The transfer resource that dynamic dispatching is assigned authenticates temporarily at the cell-radio network of client that (CellRadio Network Temporary Identifier C-RNTI) sends; The transfer resource that semi-persistent scheduling is assigned then authenticates (SPSC-RNTI) at the semi-persistent scheduling cell-radio network of client temporarily and sends.Wherein, the interim authentication of semi-persistent scheduling cell-radio network is that radio resource control layer (RRC) is distributed to the specific user identification that semi-persistent scheduling uses, it mainly contains following two kinds of functions: start or revise the transfer resource of semi-persistent scheduling, and the re-transmission of indication semi-persistent scheduling.
For dynamic dispatching, client can be according to the hybrid automatic repeat request flow process identification code that is comprised in the physical downlink control channel signaling (Hybrid Automatic Repeat RequestProcess Identifier, HARQ Process ID) and new data indicator (New Data Indicator, NDI) field is judged being transmitted as and newly transmitting or a re-transmission corresponding to transfer resource assigns.If the value of the last time new data indicator of the value of new data indicator and same hybrid automatic repeat request flow process is different, representative this time is transmitted as a transmission newly.On the contrary, if identical with the value of the last time new data indicator of same hybrid automatic repeat request flow process, then representative this time is transmitted as a re-transmission.
For semi-persistent scheduling, the meaning of new data indicator representative is also inequality.Network terminal is indicated the function of the physical downlink control channel signaling that sends to the interim authentication of semi-persistent scheduling cell-radio network by the value of new data indicator.If the value of received new data indicator is 0, representative sends to the transfer resource that the interim physical downlink control channel signaling that authenticates of semi-persistent scheduling cell-radio network is used for starting or revising semi-persistent scheduling.On the contrary, if the value of received new data indicator is 1, then representative sends to the interim physical downlink control channel signaling that authenticates of semi-persistent scheduling cell-radio network and is used for assigning transfer resource carries out semi-persistent scheduling to client re-transmission.
According to present standard, in the down link direction, network terminal can be utilized radio resource control signaling, sets one or more hybrid automatic repeat request flow process identification codes that reservation is used to semi-persistent scheduling; The uplink direction then is after the starting point of fixed cycle and Cycle Length setting, just can learn one or more hybrid automatic repeat request flow process identification codes that reservation is used to semi-persistent scheduling.Yet in up link and down link direction, dynamic dispatching also allows to use the hybrid automatic repeat request flow process that keeps to semi-persistent scheduling.In this case, when client receives new data indicator corresponding to same hybrid automatic repeat request flow process in regular turn, and it is contained in respectively when sending to the physical downlink control channel signaling that the semi-persistent scheduling cell-radio network authenticates temporarily and cell-radio network authenticates temporarily, because the meaning difference of new data indicator field representative, therefore as if the words that the value in both new data indicator fields is compared, the result understands meaningless, even the comparison that might lead to errors, cause the mistake of transfer of data.
For instance, receive the physical downlink control channel signaling that sends to the interim authentication of semi-persistent scheduling cell-radio network when client, and it is used to refer to client and uses a certain hybrid automatic repeat request flow process, X for example, when carrying out the re-transmission of semi-persistent scheduling, the value of according to the above description, received new data indicator is 1.Then, client receives the physical downlink control channel signaling that sends to the interim authentication of cell-radio network, and it also indicates client to use identical hybrid automatic repeat request flow process X transmission data.In this case, client can be compared the new data indicator that dynamic dispatching sends with the last new data indicator of hybrid automatic repeat request flow process X, that is the new data indicator of semi-persistent scheduling transmission.Yet as previously mentioned, the new data indicator that semi-persistent scheduling sends is different with the meaning of the new data indicator representative that dynamic dispatching sends.Therefore, if the value in both new data indicator fields is compared, the result understands meaningless, even the comparison that might lead to errors, and causes the mistake of transfer of data.

Step 400: beginning.
Step 402: set a semi-persistent scheduling feature, this semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.
Step 404: receive one first new data indicator of the interim authentication of a semi-persistent dispatching cell radio network be assigned to this client, this first new data indicator is to one first hybrid automatic repeat requestor in should at least one hybrid automatic repeat requestor.
Step 406: receive the interim authentication of a cell-radio network that is assigned to this client and during in the next one, this first hybrid automatic repeat requestor waited to receive the transmission first time that transmission is considered as this first hybrid automatic repeat requestor to one second new data indicator that should the first hybrid automatic repeat requestor.
Step 408: finish.
According to flow process 40, the embodiment of the invention is at first set the semi-persistent scheduling function of client, and the semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.Then, the embodiment of the invention receives first new data indicator of the interim authentication of semi-persistent scheduling cell-radio network that is assigned to client.The first hybrid automatic repeat requestor in the corresponding at least one hybrid automatic repeat requestor of first new data indicator.At last, when the embodiment of the invention receives second new data indicator of interim authentication of the cell-radio network that is assigned to client and the corresponding first hybrid automatic repeat requestor in the next one, the first hybrid automatic repeat requestor waited to receive the transmission first time that transmission is considered as the first hybrid automatic repeat requestor.
As described in prior art, network terminal is utilized Radio Resource control (Radio Resource Control, RRC) signaling is set the semi-persistent scheduling of client, for example: the number of the pairing hybrid automatic repeat request of at least one hybrid automatic repeat requestor flow process.In addition, the dynamic dispatching transfer resource of assigning is that cell-radio network at client authenticates temporarily that (Cell Radio NetworkTemporary Identifier C-RNTI) sends; The transfer resource that semi-persistent scheduling is assigned then authenticates (SPS C-RNTI) at the semi-persistent scheduling cell-radio network of client temporarily and sends.Wherein, the new data indicator that semi-persistent scheduling sends, promptly be contained in the new data indicator in the physical downlink control channel signaling that is assigned to the interim authentication of semi-persistent scheduling cell-radio network, mainly contain following two kinds of functions: the indication client is revised the setting of semi-persistent scheduling function, or the re-transmission of reception semi-persistent scheduling function, it is known by those skilled in the art, does not add to give unnecessary details at this.
Therefore, when client receives first new data indicator and second new data indicator corresponding to same hybrid automatic repeat request flow process in regular turn, and it is when being contained in the physical downlink control channel signaling that sends to interim authentication of semi-persistent scheduling cell-radio network and the interim authentication of cell-radio network respectively, and the embodiment of the invention waits to receive the transmission first time that transmission is considered as the hybrid automatic repeat requestor with the hybrid automatic repeat requestor.
For instance, please continue with reference to figure 5, Fig. 5 is the running schematic diagram of embodiment of the invention flow process 40.Suppose that client receives first new data indicator that sends to interim authentication of semi-persistent scheduling cell-radio network and corresponding hybrid automatic repeat requestor X in a time point B1, and time point E1 and F1 semi-persistent scheduling resource for having reserved, then in time point C1, receive send to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X second new data indicator.As described in prior art, different with the meaning of representing corresponding to the new data indicator of the interim authentication of cell-radio network corresponding to the new data indicator of the interim authentication of semi-persistent scheduling cell-radio network.Therefore, the embodiment of the invention waits to receive the transmission first time that transmission is considered as hybrid automatic repeat requestor X with the hybrid automatic repeat requestor X of time point C1.Simultaneously, no matter whether (as: a time point A1) receives one the 3rd new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X before time point B1, the embodiment of the invention without exception with the hybrid automatic repeat requestor X of time point C1 wait receive the transmission very for the first time that transmission is considered as hybrid automatic repeat requestor X, that is new transmission.Thus, the embodiment of the invention can be avoided new data indicator is carried out mistake relatively, and the transfer of data that makes the mistake.
Be noted that, suppose after receiving second new data indicator, also receive the "four news" (new ideas data pointer that the cell-radio network that sends to authenticated temporarily and corresponded to hybrid automatic repeat requestor X in a time point D1.In the case, because second new data indicator and "four news" (new ideas data pointer all belong to the new data indicator that dynamic dispatching sends, therefore client can compare the value of second new data indicator and "four news" (new ideas data pointer, and judges that hybrid automatic repeat requestor X's waits whether receive transmission is new transfer of data.Wherein, if the value of the "four news" (new ideas data pointer and second new data indicator is identical, the reception for the treatment of of hybrid automatic repeat requestor X is transmitted as data retransmission; If the value of "four news" (new ideas data pointer and second new data indicator is different, then hybrid automatic repeat requestor X's waits to receive and is transmitted as new transfer of data.
In the same manner, suppose that it is the re-transmission of a time point B2 semi-persistent scheduling that client receives first new data indicator that sends to interim authentication of semi-persistent scheduling cell-radio network and corresponding hybrid automatic repeat requestor X in a time point C2, and time point F2 and G2 semi-persistent scheduling resource for having reserved, then in time point D2, receive second new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X, the embodiment of the invention waits to receive the transmission first time that transmission is considered as hybrid automatic repeat requestor X with the hybrid automatic repeat requestor X's of time point D2.Simultaneously, no matter whether (as: a time point A2) receives one the 3rd new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X before time point B2, the embodiment of the invention without exception with the hybrid automatic repeat requestor X of time point D2 wait receive the transmission very for the first time that transmission is considered as hybrid automatic repeat requestor X, that is new transmission.In addition, suppose after receiving second new data indicator, also receive the "four news" (new ideas data pointer that the cell-radio network that sends to authenticated temporarily and corresponded to hybrid automatic repeat requestor X in a time point E2, can the value of second new data indicator and "four news" (new ideas data pointer be compared, that judges hybrid automatic repeat requestor X waits whether receive transmission is new transfer of data.
Please refer to Fig. 6, Fig. 6 is the schematic diagram of another embodiment of the present invention one flow process 60.The client that flow process 60 is used for a wireless telecommunication system is handled the method for the hybrid automatic repeat requestor of semi-persistent scheduling function, and it also can be compiled as hybrid automatic repeat requestor handling procedure 220.Flow process 60 comprises following steps:
Step 600: beginning.
Step 602: set a semi-persistent scheduling feature, this semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.
Step 604: according to this semi-persistent scheduling function, receive the default transmission be assigned to this client, and should transmission to one first hybrid automatic repeat requestor in should at least one hybrid automatic repeat requestor.
Step 606: receive the interim authentication of a cell-radio network that is assigned to this client and to should the first hybrid automatic repeat requestor time in the next one, this first hybrid automatic repeat requestor waited to receive the transmission first time that transmission is considered as this first hybrid automatic repeat requestor.
Step 608: finish.
According to flow process 60, the embodiment of the invention is at first set the semi-persistent scheduling function of client.The semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.Then, embodiment of the invention reception is assigned to a default transmission of this client and the first hybrid automatic repeat requestor in corresponding at least one hybrid automatic repeat requestor.At last, when the embodiment of the invention receives interim authentication of the cell-radio network that is assigned to client and the corresponding first hybrid automatic repeat requestor in the next one, the first hybrid automatic repeat requestor waited to receive the transmission first time that transmission is considered as the first hybrid automatic repeat requestor.
For instance, please continue with reference to figure 7, Fig. 7 is the running schematic diagram of embodiment of the invention flow process 60.Suppose that client receives the semi-persistent scheduling resource that sends to interim authentication of semi-persistent scheduling cell-radio network and corresponding hybrid automatic repeat requestor X in a time point A3, and time point C3 and the F3 semi-persistent scheduling resource for having reserved, wherein the semi-persistent scheduling of the reservation resource of time point C3 corresponds to hybrid automatic repeat requestor X.Then in a time point D3, receive second new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X, the embodiment of the invention waits to receive the transmission first time that transmission is considered as hybrid automatic repeat requestor X with the hybrid automatic repeat requestor X's of time point D3.Simultaneously, no matter whether (as: a time point B3) receives the 3rd new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X before time point C3, the embodiment of the invention without exception with the hybrid automatic repeat requestor X of time point D3 wait receive the transmission very for the first time that transmission is considered as hybrid automatic repeat requestor X, that is new transmission.In addition, suppose after the time point D3, also receive in a time point E3 and to send to the "four news" (new ideas data pointer that cell-radio network authenticated temporarily and corresponded to hybrid automatic repeat requestor X, can the value of second new data indicator and "four news" (new ideas data pointer be compared, that judges hybrid automatic repeat requestor X waits whether receive transmission is new transfer of data.
Please refer to Fig. 8, Fig. 8 is the schematic diagram of another embodiment of the present invention one flow process 80.The client that flow process 80 is used for a wireless telecommunication system is handled the method for the hybrid automatic repeat requestor of semi-persistent scheduling function, and it also can be compiled as hybrid automatic repeat requestor handling procedure 220.Flow process 80 comprises following steps:
Step 800: beginning.
Step 802: set a semi-persistent scheduling feature, this semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.
Step 804: receive one first new data indicator of the interim authentication of a cell-radio network be assigned to this client, this first new data indicator is to one first hybrid automatic repeat requestor in should at least one hybrid automatic repeat requestor.
Step 806: according to before being assigned to the interim authentication of this cell-radio network and to one second new data indicator that should the first hybrid automatic repeat requestor and this first new data indicator relatively, that judges this first hybrid automatic repeat requestor waits to receive whether transmit be new data; Wherein receiving between this first new data indicator and this second new data indicator, this client has received one the 3rd new data indicator of the interim authentication of a semi-persistent dispatching cell radio network that is assigned to this client, or receives the default transmission that is assigned to this client and to should the first hybrid automatic repeat requestor.
Step 808: finish.
According to flow process 80, the embodiment of the invention is at first set the semi-persistent scheduling function of client.The semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.Then, the embodiment of the invention receives first new data indicator of the interim authentication of cell-radio network that is assigned to client.The first hybrid automatic repeat requestor in the corresponding at least one hybrid automatic repeat requestor of first new data indicator.At last, the embodiment of the invention compares according to second new data indicator that before was assigned to interim authentication of cell-radio network and the corresponding first hybrid automatic repeat requestor and first new data indicator, and that judges the first hybrid automatic repeat requestor treats whether the reception transmission is new data.Be noted that, in step 806, in receiving between first new data indicator and second new data indicator, client has received the 3rd new data indicator of the interim authentication of semi-persistent scheduling cell-radio network, or receives semi-persistent transfer resource and the corresponding first hybrid automatic repeat requestor of keeping for client.
For instance, please refer to Fig. 9, Fig. 9 is the running schematic diagram of embodiment of the invention flow process 80.Suppose that client receives the 3rd new data indicator that sends to interim authentication of semi-persistent scheduling cell-radio network and corresponding hybrid automatic repeat requestor X in a time point B4, and time point D4 and the semi-persistent scheduling resource of E4 for having reserved.Then, in time point C4, receive first new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X.In embodiments of the present invention, client can be according to second new data indicator (as the time point A4 among the figure) that before was assigned to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X, and that judges hybrid automatic repeat requestor X waits whether receive transmission is new transfer of data.If the value of first new data indicator and second new data indicator is identical, client judges that the reception for the treatment of of hybrid automatic repeat requestor X is transmitted as data retransmission; On the contrary, if the value of first new data indicator and second new data indicator is different, then judge waiting to receive and being transmitted as new transfer of data of hybrid automatic repeat requestor X.
On the other hand, equally in Fig. 9, suppose that client receives the semi-persistent transfer resource that sends to interim authentication of semi-persistent scheduling cell-radio network and corresponding hybrid automatic repeat requestor X in a time point A5, and time point C5 and the semi-persistent scheduling resource of E5 for having reserved.Then, in time point D5, receive first new data indicator that sends to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X.In embodiments of the present invention, client can be according to second new data indicator (as the time point B5 among the figure) that before was assigned to interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X, and that judges hybrid automatic repeat requestor X waits whether receive transmission is new transfer of data.If the value of first new data indicator and second new data indicator is identical, client judges that the reception for the treatment of of hybrid automatic repeat requestor X is transmitted as data retransmission; On the contrary, if the value of first new data indicator and second new data indicator is different, then judge waiting to receive and being transmitted as new transfer of data of hybrid automatic repeat requestor X.
That is to say, under the situation that the semi-persistent scheduling function is enabled, when client receives the new data indicator that sends to the interim authentication of cell-radio network, the embodiment of the invention was only to before sending to the interim authentication of cell-radio network and comparing corresponding to the new data indicator of the automatic re-send request may program of same mixture formula, avoiding because of mistake new data indicator relatively, and the transfer of data that makes the mistake.
Be noted that, if when there are not second new data indicator of interim authentication of cell-radio network and corresponding hybrid automatic repeat requestor X in time point A4 and B5, the embodiment of the invention waits to receive the transmission first time that transmission is considered as hybrid automatic repeat requestor X with hybrid automatic repeat requestor X's.
Please refer to Figure 10, Figure 10 is the schematic diagram of another embodiment of the present invention one flow process 90.The client that flow process 90 is used for a wireless telecommunication system is handled the method for the hybrid automatic repeat requestor of semi-persistent scheduling function, and it also can be compiled as hybrid automatic repeat requestor handling procedure 220.Flow process 90 comprises following steps:
Step 900: beginning.
Step 902: set a semi-persistent scheduling feature, this semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.
Step 904: receive a semi-persistent dispatching cell radio network that is assigned to this client and authenticate this client releasing semi-persistent scheduling setting of indication temporarily.
Step 906: this client is removed the pairing buffer contents of this at least one hybrid automatic repeat requestor, or with the next one be assigned to this client the interim authentication of a cell-radio network and to should at least one hybrid automatic repeat requestor wait receive transmission, be considered as the transmission first time of this at least one hybrid automatic repeat requestor.
Step 908: finish.
According to flow process 90, the embodiment of the invention is at first set the semi-persistent scheduling function of client.The semi-persistent scheduling function is used at least one hybrid automatic repeat requestor.Then, the embodiment of the invention receives and indicates the semi-persistent scheduling cell-radio network of client releasing semi-persistent scheduling setting to authenticate temporarily.At last, client is removed the pairing buffer contents of at least one hybrid automatic repeat requestor, or with the next one be assigned to the interim authentication of cell-radio network of client and corresponding at least one hybrid automatic repeat requestor wait receive transmission, be considered as the transmission first time of at least one hybrid automatic repeat requestor.
Therefore, from the above, when client in receive when removing semi-persistent scheduling cell-radio network that semi-persistent scheduling sets and authenticating temporarily, the invention process regular meeting will correspond to the buffer contents of at least one hybrid automatic repeat requestor and remove, or wait to receive transmission with what the next one sent to the interim authentication of cell-radio network and corresponding at least one hybrid automatic repeat requestor, be considered as transmission for the first time, to avoid that the mistake of new data indicator is compared the transfer of data that makes the mistake.
In brief, because the new data indicator that semi-persistent scheduling sends is different with the meaning that the new data indicator that dynamic dispatching sends is represented, therefore, for the new data indicator of avoiding different meanings is carried out wrong comparison, the embodiment of the invention provides four kinds of settling modes, first kind is that pairing the waiting of the interim authentication of next cell-radio network after the interim authentication of semi-persistent cell-radio network received transmission, is considered as the transmission very for the first time of hybrid automatic repeat requestor; Pairing the waiting of the interim authentication of next cell-radio network after the semi-persistent scheduling resource that the second way will have been reserved receives transmission, is considered as the transmission very for the first time of hybrid automatic repeat requestor; The third mode only compares at the new data indicator that before sent to interim authentication of cell-radio network and the automatic re-send request may program of corresponding same mixture formula; The 4th kind of mode then is when receiving the setting of releasing semi-persistent scheduling, remove the pairing buffer contents of at least one hybrid automatic repeat requestor, or pairing the waiting of the interim authentication of next cell-radio network received transmission, be considered as the transmission very for the first time of hybrid automatic repeat requestor.Thus, the embodiment of the invention can be avoided the comparison that makes a mistake, prevents wrong transfer of data.
In sum, the embodiment of the invention provides the method for the hybrid automatic repeat requestor of handling the semi-persistent scheduling function, avoiding wrong transfer of data, and then improves the correctness of transfer of data.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
